each seller has there own warranty. Check with the sellers site first. Mine had a 90 day warranty. it works good although the battery door is cheap and falls off at times. You can put it back on easily. If its mounted it stays but if you move it around tends to fall off its worth the money id say Good Luck
I don't know exactly what the warranty was on the car DVR camera. I did not write a very favorable review, but I am liking it more as I use it more. So far so good. The video is not high definition, but it's good enough. A high grade SD card helps a lot. I hope this helps if you are thinking of getting one.
